Abstract
A stereophonic warning apparatus for a vehicle is provided with a judging device which judges warning priority level relative to an object around the vehicle according to signals from radars for detecting the object and a vehicle behavior detecting device. A control device controls the output level of a plurality of speakers in a passenger compartment of the vehicle according to the position of the detected object such that the speakers output a warning sound to form a sound image at a position to which the detected object is located, while changing the warning sound according to the warning priority level.
